then run time will be 0.08*500 = 40 min / board. Therefore‚ time taken to drill N boards manually will be equal to : 15 + 40(N) * On the other hand the CNC drill needs 240 min for set up‚ in addition to 0.004 min for every hole. So run time will be 0.004*500 = 2 min / board. Then the time taken to drill N boards by CNC drill will be equivalent to : 240 + 2(N) * It is then logic to conclude that we will use CNC drill only in order sizes that will provide timing benefit over manual press. i
